LP SOLIDSTART OSB & LSL RIM BOARD Floor & Roof Applications Limit States Design Product Specifications & Design Values LP® SOLIDSTART® RIM BOARD MATERIALS & FABRICATION An integral part of LP’s framing package, OSB and LSL LP offers two types of rim board: LP SolidStart OSB Rim Board from LP Engineered Wood Products provides Rim Board, fabricated from oriented strand board, and LP strong, cost-effective solutions to your framing needs. SolidStart LSL Rim Board, from Laminated Strand Lumber Designed to match our LP SolidStart I-Joists, they are (LSL). Both types are precision cut to match the depths of available in several depths and thicknesses. LP’s SolidStart LP SolidStart I-Joists. Rim Board offers straightforward and quick installation as The type of rim board you choose will depend on well as high-strength reliability. your specific project. OSB rim board comes in smaller thicknesses and is perfect for lower lateral load THE ROLE OF RIM BOARD IN A BUILDING applications. Use LSL rim board where loads are higher LP SolidStart Rim Board fills the space between the sill such as in commercial and multi-family structures. plate and the bottom wall plate, or between the top plate and bottom plate in multi-story construction. In addition to BEAM & HEADER STOCK AS RIM BOARD filling the void, rim board is an integral structural While standard LP LSL may appear to be suited for use as component that transfers both lateral and vertical forces. rim board, there are several reasons why it may not be the To function properly, rim board must match the depth of best choice, including different tolerances on the finished framing members. Traditional solid sawn lumber typically depth and labeling requirements: does not match engineered wood I-Joists, which is why LP • Rim Board products are ripped slightly taller than an SolidStart Rim Board is a perfect choice. Even for seemingly I-Joist to ensure that all vertical load is transferred similar depths, lumber can shrink leaving it shorter than the through the rim board rather than through the I-Joist.

Here are just a few of the benefits: Trouble-Free Workability • Easy to saw, drill, plane, file or sand with normal carpentry tools • I-Joist compatible depths save time on the job-site • Flat surfaces for easy installation of siding • Precut depths means less inaccuracies and time involved in ripping in the field Just The Right Size • I-Joist compatible depths for a perfect match • LP SolidStart LSL may be available in longer lengths LP SOLIDSTART RIM BOARD PROFILES Fire Blocking • 1" or thicker LP SolidStart Rim Board can be used as an alternate to 23/32" wood structural panel fire blocking • 1-1/4" or thicker LP SolidStart Rim Board can be used as an alternate to nominally 2" lumber fire blocking 9-1/2," 11-7/8," SPECIFIED RIM BOARD WEIGHTS (PLF) 14," 16," Rim Board Depth 1 8 ," 2 0 ," Type Thickness 9-1/2" 11-7/8" 14" 16" 18" 20" 22" 24" and 24" LP OSB 1-1/8" 2.9 3.6 4.3 4.8 5.5 6.1 6.7 7.3 1-1/4" 3.9 4.9 5.8 6.2 7.3 8.1 8.8 9.6 LP LSL 1-1/2" 4.7 5.9 7.0 7.9 8.8 9.7 10.6 11.5 LP SolidStart LP SolidStart OSB Rim Board LSL Rim Board 2 Product Specifications & Design Values FACTORED RIM BOARD RESISTANCE Vertical Load Resistance Lateral Load4,5,6 Material Grade Thickness Uniform Concentrated Resistance, d ≤ 16" 16" < d ≤ 24" d ≤ 24" fH (plf) LP OSB APA C1/Rim Board7 1-1/8" 7339 5004 5838 235 1-1/4" 10008 6338 6338 326 LP LSL 1.35E ≥ 1-1/2" 11676 7506 7506 365 NOTES: 1. The Factored Vertical Load Resistance shall not be increased for short-term load duration. 2. The Factored Vertical Load Resistance is based on the resistance of the rim board and may need to be reduced based on the bearing resistance of the supporting wall plate or the attached floor sheathing. Example: The factored bearing resistance for OSB floor sheathing is 487 psi so the bearing resistance of a 1-1/4" x 16" deep rim board would be limited to 7305 plf (487 psi x 1-1/4" x 12). 3. The Factored Concentrated Vertical Load Resistance is assumed to be applied through a minimum 4-1/2" bearing length (3-stud post). 4. The Factored Lateral Load Resistance is based on a short-term load duration and shall not be increased. 5. The Factored Lateral Load Resistance is based on the connections specified in the Installation details on page 4. 6. Additional framing connectors fastened to the face of the rim board may be used to increase lateral resistance for wind and seismic design. 7. APA C1 grade in product standard ANSI/APA PRR 410-2011 is equivalent to the rim board grade in product standard APA PRR-401C.

This table is for preliminary design for uniform gravity loads only. Final design should include a complete analysis of all loads and connections. 2. The factored load resistances are for a maximum 4' clear span with minimum bearings for each end (listed in parentheses) based on the bearing resistance of the rim board. For headers bearing on wood plates, the bearing length may need to be increased based on the ratio of the bearing resistance of the rim board divided by the bearing resistance of the plate species. 3. Standard load duration is assumed and shall be adjusted according to code. 4. Depths greater than 11-7/8" shall be used with a minimum of two plies, as shown. Depths of 11-7/8" and less may be used as a two-ply header by multiplying the resistance by two. 5. Multiple-ply headers shall be toe-nailed to the plate from both faces. Fasten the floor sheathing to the top of each ply to provide proper lateral support for each ply. 6. For multiple-ply headers supporting top-loads only, fasten plies together with minimum 2-1/2" nails (common wire or spiral) at a maximum spacing of 12" oc. Use 2 rows of nails for 9-1/2" and 11-7/8". Use 3 rows for depths 14" and greater. Clinch the nails where possible. For side-loaded multiple-ply headers, refer to the Connection Resistance For Side-Loaded 2-Ply Rim Board Headers table below for the required nailing and the maximum side load that can be applied. 7. The designer shall verify proper bearing for the header. 8. Joints in the rim are not allowed over openings and must be located at least 12" from any opening. 9. Refer to the "APA Performance Rated Rim Boards - Limit States Design" (Form No. D340 CA) for additional information including uniform load resistance for smaller openings. 10. Use LP® SolidStart® LSL for headers with clear spans longer than 4' or for loads greater than tabulated above. See the Design Values table below.

LP SolidStart LSL and OSB Rim Board shall be designed for dry-use conditions only. Dry-use applies to products installed in dry, covered and well ventilated interior conditions in which the equivalent average moisture content in lumber will not exceed 15% nor a maximum of 19%. Adjustments for high temperature are beyond the scope of this guide. 2. The specified strengths and stiffness are for standard load duration. Bending, Shear and Compression perpendicular-to-grain, shall be adjusted according to code. Modulus of Elasticity shall not be adjusted for load duration. 3 The specified strengths and stiffness are for members supporting loads applied parallel to the wide face (“edge” or “beam” orientation). 4. The specified Bending, fb, for LP SolidStart OSB Rim Board has been adjusted to account for volume for clear spans up to 4'. Do not use for clear spans over 4'. 0.120 5. The specified Bending, fb, for LP SolidStart LSL is tabulated for a standard 12" depth. For depths other than 12", multiply fb by (12/depth) . For depths less than 3-1/2", adjust fb by 1.159.
